The ending of the series varies greatly from the novel. In the novel, Colonel Cathcart offers to send Yossarian home if he agrees to stop his nude protest and publicly support the colonel's plan to raise the number of missions. After agreeing to this, Yossarian is stabbed by Nately's girlfriend, who went crazy after his death. As he recuperates, he reflects on Snowden's death and decides not to accept the deal. The chaplain informs Yossarian that Orr, whom everyone believed to be almost mentally deficient, had escaped to Sweden as part of a long-plotted escape. Inspired, Yossarian runs off, with Nately's knife-wielding girlfriend on his tail.
